Thanks Flash and Billy-
Flash- That is more or less the process I have followed on this, over a long time. Resistances were all good, some connectors were questionable-they were replaced/cleaned. However all this was spread out over a period of many months, since many of my fixes (cleaning contacts, replacing the sensor connector, etc) seemed to work for 100's of driven miles making me think it was fixed. I haven't tried intentionally shorting out the sensor leads and seeing what code get create, but since there are only two related to the cam sensor codes (0340 and 0344 which is the intermittent version) in the FSM not sure that a direct short would show anything different, at least from Torque and my OBDII reader, maybe on a DRBIII.
Billybob- sounds like that crash created a real nightmare. And like you, I may be chasing a few hidden bad wires somewhere, I am just not entirely sure yet.
What I was hoping the experts here could comment on was my previous thought that even though the exhaust pin would not go in the last 1/8" the TBelt alignment is good.
When I thought about this some more, it seem to be saying: the crank and intake cam are perfectly aligned (their pins go in all they way easily), but the exhaust cam may be a few degress off. Gee the exhaust cam may be off a few degrees, the one the cam sensor is on, think that might cause the p0340
Although I have done a few Tbelts and chains on other engines, I am still a novice on these CRDs. I don't have the experience to say "hey a pin not going in the last little bit is pretty common" or "that's the problem you gotta reset that tBelt timing". Either seems possible to me, with what I am seeing now. Knowing what the timing window the ECU has for the cam would help too. I plan on playing around with the intake manifold on the bench some more to get a better estimate of how many degrees off would cause the pin to bind 1/8" out. And when weather permits checking to see if with no other pins that exhaust cam pin can go all the way at some rotation (also may yield an estimate of degrees off), if so it would be definite that the ex cam is timed off a bit.
So what do the experts think? Should I be looking closer at the exhaust cam timing, or lay the mechanical stuff to rest and pull out the VOM again? All thoughts, theories, ideas appreciated.
